Description

Belt storage apparatus for synchronous conveyor

Technical field:

The utility model relates to a kind of equipment that tunnels the tunnel, particularly a kind of equipment of removing or transporting excavated material.

Background technology:

In existing tunnel (or underworkings) tunneling process, the material earth of its generation or spoil etc. are transported to ground from the tunnel, be to adopt the batch (-type) means of transportation, tunnel as subway tunnel, adopt shield excavation machine, with material earth or spoil extruding or broken, by the conveying worm that is provided with in the shield excavation machine, material is extruded into the redoiming conveyor that the shield excavation machine rear side is provided with, is loaded in the body feed tank, be transported to the tunnel well head by electric locomotive (locomotive battery or stringing) traction then, by elevator material is transported to ground again, be discharged to interim windrow field boundary, electric locomotive returns back to the shield excavation machine place along track simultaneously, remakes conveying next time; Be transported in the process of material field from shield excavation machine at above-mentioned material; because material is output in time; shield excavation machine has to stop excavation operation; and the ineffective time of formation operation; reduce excavation operation efficient; the time that above-mentioned electric locomotive comes and goes in the tunnel; along with the distance of shield excavation machine and well head increases and prolongs, in tunneling process, this may reach km to thousands of rice apart from major part; and the gait of march of electric locomotive normally 8 kms/hour; obviously be very long the downtime of shield excavation machine, therefore, will have a strong impact on drivage efficiency; its loss economically is very big, and brings negative social effect simultaneously.How above-mentioned discontinuous means of transportation being changed into continuous means of transportation, improve tunnel piercing efficient, is the technical problem that the dealer needs to be resolved hurrily.

The utility model content:

Technical problem to be solved in the utility model is, a kind of belt storage apparatus for synchronous conveyor is provided, it can make the conveyer belt of synchronous conveyor, prolong synchronously along with the prolongation of the driving process of shield excavation machine, the material that excavation operation produces can be delivered to well head from shield excavation machine continuously, improves excavation operation efficient.

The technical scheme in the invention for solving the above technical problem is: belt storage apparatus includes bogie, the storehouse frame, the carrying roller dolly, dolly and tensioning apparatus move about, bogie is connected with the storehouse frame, be provided with the carrying roller dolly in the frame of storehouse, dolly and tensioning apparatus move about, the conveyer belt of synchronous conveyor stretches into belt storage apparatus from head, conveyer belt in belt storage apparatus is the multilayer pitch of the laps in the cylinder group of bogie and the cylinder group of the dolly that moves about, conveyer belt is connected in tail at the end that goes out of belt storage apparatus, at bogie with move about and be provided with the carrying roller dolly between the dolly, the carrying roller of carrying roller dolly supports each layer conveyer belt respectively, and the cable wire of tensioning dress is connected with the dolly that moves about.Conveyer belt goes out end at belt storage apparatus and is drawn by tail through fuselage, when the shield excavation machine drive tail that advances, tail traction conveyer belt extends thereupon synchronously, simultaneously, utilize tensioning apparatus winch pull line, make that the dolly that moves about moves, tensioning and change the length of the conveyer belt of multilayer folding.

The structure of the multilayer folding conveyer belt that each cylinder group of the utility model mat belt storage apparatus forms, the conveyer belt of storage preseting length, and with its change belt length feature, can keep the synchronous transport function to extend synchronously with shield excavation machine driving progress, thereby the material earth that driving is produced, spoil etc., be delivered to well head from shield excavation machine continuously, fundamentally overcome the defective of tradition with electric locomotive intermittent delivery material, tunnel piercing speed can be increased to 17～18 meters of average every days by 7～8 meters of former average every days, improve drivage efficiency greatly, have remarkable economic efficiency and social benefit.
